Jacob is a kind, caring red-orange-haired individual with English/Scottish heritage in his blood with a strong love of dragon-type (as well as dragon-like and dragon egg group) Pokémon and a love for children. He is currently working on becoming a Dragon Master and an author for children's books.

Possesses a dry sense of humor and has very little patience for trainers that he considers or sees to be upstarts, braggarts, con-artists, bullies, poachers, terrorists, even racists, bigots and Dragon-type haters. Also possesses a strong hatred for high-heels (he considers that kind of footwear to be an accident waiting to happen) and snow and bitter cold, but will put it aside for things such as the Christmas holidays and his birthday.

Not very comfortable about talking about his deceased estranged father, due to an unhappy relationship with him. Because of this, Jacob feels much comfortable being around his grandfather, who's been more of a father to him than anything.

Because he was upset at his mother's death when he turned 10, Jacob didn't start his Pokémon journey until he turned 12, along with some encouragement from his grandparents.

Jacob keeps a notebook with him with which he writes down ideas for any future stories he may work on. Always looking for inspiration, Jacob has travelled across different parts of the world - from Unova, to Johto, Sinnoh, Hoenn and Kanto - challenging other trainers and gym leaders in order to grow stronger. Already having triumphed over Clair and Drayden, he hopes to challenge the Kanto/Johto Pokémon League Champion Lance someday.
